Abstract
A major contribution to the shift of cluster core level binding energies with respect to cluster size is established. Core ionized cluster atoms with higher coordination have binding energies smaller than atoms with lower coordination. This is an initial state effect associated with the amount of valence charge density which surrounds the ionized atom. It is also shown that macroscopic Coulomb charging effects for the ionized cluster final state do not make a significant contribution to the binding energy shifts for micro-clusters.
